WARNING: This page is about a different variant/trim than selected.
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review GENERAL TROUBLESHOOTING INFORMATION .
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P0976 is stored in the PCM, the transmission does not shift to any gear other than 1st, 2nd, or 5th gear because of the fail-safe function.
- Turn the ignition switch to ON (II).
